### API Reference

#### Core
> `dd.asset` builds an asset from a schema, and `quarantine_spec` adds that asset's quarantine to the asset graph.

- [asset](https://ozanozbeker.com/dagster-dataframely/reference/asset.html): Turn the decorated function into an asset that validates the frame it returns against `schema`
- [quarantine_spec](https://ozanozbeker.com/dagster-dataframely/reference/quarantine_spec.html): Return an asset spec that adds an asset's quarantine to the asset graph
- [Granularity](https://ozanozbeker.com/dagster-dataframely/reference/Granularity.html): Type alias
- [SchemaRules](https://ozanozbeker.com/dagster-dataframely/reference/SchemaRules.html): Type alias

#### Hand-wiring
> `dd.asset` assembles these parts. Use them to build a `@dg.asset` yourself, where `dd.asset` does not fit.
